UnitedHealthcare ends GI site-of-service review Oct. 1 — the friction it drops sat on hospitals, not ASCs
A UnitedHealthcare notice posted September 1 stops advance notification for EGD, capsule endoscopy and diagnostic and surveillance colonoscopy from October 1 — and in the same paragraph ends site-of-service medical-necessity review, which the payer conditioned on the outpatient hospital setting.

- From October 1, 2026, UnitedHealthcare will no longer request advance notification for esophagogastroduodenoscopies, capsule endoscopies, and diagnostic and surveillance colonoscopies.
- The same notice ends site-of-service medical-necessity review for these services performed in an outpatient hospital setting, and extends that to screening colonoscopy, which was never subject to advance notification.
- The change covers UnitedHealthcare commercial plan and Oxford New York and Connecticut plan members; the notice does not extend it to Medicare Advantage.
- Advance notification, by UnitedHealthcare's own standing terms, never produced administrative denials for non-submission — so the notification half is lighter than it reads.
UnitedHealthcare will stop asking for advance notification on most gastrointestinal endoscopy from October 1, 2026 — and in the same notice, it retires the review that actually steered those cases.
The insurer’s provider announcement, posted September 1, says that “to help simplify access to care and reduce complexity, beginning Oct. 1, 2026, we’ll no longer request advance notification” for esophagogastroduodenoscopies, capsule endoscopies, and diagnostic and surveillance colonoscopies. It covers UnitedHealthcare commercial plan and Oxford New York and Connecticut plan members.
The sentence that matters for facility economics is the next one: “When these services are performed on or after Oct. 1, 2026, SOS medical necessity review will no longer be required if performed in an outpatient hospital setting.” Site-of-service review is going away for GI across the board — including for screening colonoscopy, which the notice says “were not subject to this advance notification process” in the first place.
Site-of-service review is a steering instrument. It exists to make the costlier setting justify itself.
Both documents condition that review on one setting. Under UnitedHealthcare’s standing GI program, live since June 1, 2023, “screening colonoscopy procedures only require prior authorization for site of service medical necessity review if the service is planned at an outpatient hospital.” The trigger was the hospital outpatient department, and from October 1 it is gone.
So the natural ASC reading of this notice — a payer is cutting red tape, good for us — is close to backwards. The red tape being cut was attached to the costlier setting. What that does to where cases actually land is not something the notice says, or something ASC News can measure yet; what it plainly does is remove the mechanism.
The notification half is lighter than it sounds. UnitedHealthcare’s program page commits that it “will not issue administrative denials for failure to submit advance notification” — so the requirement being dropped carried no payment consequence for missing it. Dropping it simplifies a scheduling office’s week; it is not a coverage change.
One boundary worth marking. The notice describes ending advance notification and site-of-service review. It does not use the term prior authorization for these services, and it names no CPT codes. Characterizations elsewhere in the GI world have described the change as eliminating prior authorization for a specific handful of endoscopy codes — a different instrument with different consequences — and ASC News is not reporting that until UnitedHealthcare’s own documentation supports it.
For operators the action is narrower than the headline: ASC billing for these cases does not change on October 1. The change is to the competitive surface. Centers whose GI volume grew partly because the hospital across town had a review to clear should expect that edge to be gone — and should note it was never a rate advantage.
